Secondly, whilst retaining undiminished the full and clear directions provided for students who are starting the study of practical organic chemistry, we have extended the scope of the work so that it covers most of the needs of students working for an Honours or Special Degree. 

In the Brpnsted picture, the acid is a proton donor, but in the Lewis picture the proton itself is the acid since it has a vacant orbital. A Brpnsted acid becomes, in the Lewis picture, the compound that gives up the actual acid. The advantage of Lewis theory is that it correlates the behavior of many more processes. For example, AICI3 and BF3 are Lewis acids because they have only 6 electrons in the outer shell and have room for 8. Both SnCU and SO3 have eight, but their central elements, not being in the first row of the periodic table, have room for 10 or 12. Other Lewis acids are simple cations, like Ag. The simple reaction A + B- A—B is not very common in organic chemistry, but the scope of the Lewis picture is much larger because reactions of the types... 

Organic chemistry is blessed with a large number of books devoted to a thorough coverage of a specific area. Many of these are essentially very long review articles, differing from ordinary review articles only in size and scope. Some of the books are by a single author, and others have chapters by different authors but all are carefully planned to cover a specific area. Many of these books have been referred to in... 

As stated previously, these activities are only part of the job of the process chemist As described in Section 2 of each chapter, titled Chemistry Development , the author(s) will focus on the advancement of synthetic organic chemistry discovered during the process development. In order to satisfy the Process Chemist s scientific curiosity and to advance synthetic organic chemistry, further optimization followed by investigation of the scope and limitations of these reactions is explored. In order to ensure the robustness of the reaction and to optimize it in a more scientific way, elucidation of the reaction mechanism is undertaken. Mechanistic studies are very beneficial in improving our synthetic organic chemistry skills and provide opportunities to raise these reactions to a further dimension, again that of Art . 

Since the structures of polyester FBAs are so varied, the reactions employed in their synthesis are also diverse. The organic chemistry can be complex and the intermediates required are often difficult to prepare. A full discussion is beyond the scope of this chapter. The reader is referred, in the first place, to the reviews mentioned in the introduction for further information [3-13]. A summary of the more important methods of manufacture follows. 

All issues about the preparation of inorganic solid catalysts that we have discussed above apply for the rapid sequential synthesis of inorganic solids by automated methodologies. As for HTE - and combinatorial approaches in organic chemistry, technical solutions for compound synthesis can be obtained commercially for a number of synthetic problems [42-45] and it is beyond the scope of this chapter to discuss all the technical details. 

All these advances have resulted not only in increases in resolution but have also alleviated the detection problems to a considerable extent. As a result, the last decade has seen a dramatic growth in 15N- and 170-NMR spectroscopy as a versatile method for studying molecular structure, both in isotropic (liquid) and anisotropic (solid) phases. Studies at a natural abundance level of the nucleides are now commonplace. The scope of chemical applications extends from inorganic, organometallic and organic chemistry to biochemistry and molecular biology, and includes the study of reactive intermediates, biopolymers and enzyme-inhibitor complexes. 

In view of the expected increase in interest in this useful technique, we present here a practical guide to the literature for potential as well as for current users. First, the scope and limitation of the principles are discussed, then available programs and past applications to organic chemistry are critically reviewed. 

The second chapter, by E. Osawa and H. Musso, is entitled Application of Molecular Mechanics Calculations to Organic Chemistry. It describes the force field models presently in use as well as their scope and limitations. The authors survey the applications of these models to conformational analysis, to reaction mechanisms, to the analysis of NMR spectra, and to the design of medicinal agents. 

Hydroperoxides play an important role as oxidants in organic synthesis [56-58]. Although several methods are available for the preparation of racemic hydroperoxides, no convenient method of a broad scope was until recently [59] known for the synthesis of optically active hydroperoxides. Such peroxides have potential as oxidants in the asymmetric oxidation of organic substrates, currently a subject of intensive investigations in synthetic organic chemistry [60, 61]. The application of lipoxygenase [62-65] and lipases [66,67] facilitated the preparation of optically active hydroperoxides by enzymes for the first time.

The principle of solvent extraction—the distribution of chemical species between two immiscible liquid phases—has been applied to many areas of chemistry. A typical one is liquid partition chromatography, where the principle of solvent extraction provides the most efficient separation process available to organic chemistry today its huge application has become a field (and an industry ) of its own. The design of ion selective electrodes is another application of the solvent extraction principle it also has become an independent field. Both these applications are only briefly touched upon in the chapter of this book on analytical applications (Chapter 14), as we consider them outside the scope of... 

The book concludes by providing an outlook on possible future development in this field. Researchers and practitioners engaged in active work on synthetic or mechanistic organic chemistry and its practical applications will find this text to be invaluable in both its scope and its depth. ...
